Technical Field

[0001] This utility model relates to the technical field of packaging paperboard processing equipment, and in particular to a pusher device for preventing damage to paperboard. Background Technology

[0002] Cardboard boxes, also known as corrugated boxes, are the most widely used packaging products, made by cutting and folding cardboard. Corrugated boxes are the most widely used packaging product, consistently ranking first in usage among all packaging products. However, in current cardboard box production processes, manual feeding is time-consuming and labor-intensive. If common pusher devices are used to push the cardboard, the lack of a cushioning structure means the pusher directly pushes the cardboard into the feeding area, easily damaging the edges and leading to defective products.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0020] like Figures 1 to 3 As shown, a pusher device for preventing damage to cardboard 600 includes: a mounting frame 100, a placement component, a first pusher component, a second pusher component, and a conveying component 500; the mounting frame 100 is disposed at one end of the conveying component 500, the placement component, the first pusher component, and the second pusher component are all disposed on the mounting frame 100, and the first pusher component is disposed above one side of the placement component, and the second pusher component is disposed below one side of the placement component.

[0021] Specifically, the placement assembly includes a rotating frame 210, a lifting cylinder 220, and a placement seat 230. The rotating frame 210 is rotatably mounted on the mounting frame 100, and the lifting cylinder 220 is mounted on the rotating frame 210 and is used to drive the placement seat 230. A plug 211 is provided on the rotating frame 210, and a socket 110 is provided on the mounting frame 100. The plug 211 is movably inserted into the socket 110. A fixing pin 212 is detachably provided on the plug 211, and the fixing pin 212 is used to fix the plug 211. The first pusher assembly includes a first drive motor 310, a first lead screw 320, two first drive cylinders 330, and two first clamping cylinders 340. The first drive motor 310 and the first lead screw 320 are both mounted on the mounting bracket 100. The first drive motor 310 drives the first lead screw 320. A first slider 321 is slidably mounted on the first lead screw 320, and a first connecting rod 322 is fixedly mounted on the first slider 321. One first drive cylinder 330 is located at one end of the first connecting rod 322, and the other first drive cylinder 330 is located at the other end of the first connecting rod 322. The air rod of each first drive cylinder 330 is connected to one of the first clamping cylinders 340. Each first clamping cylinder 340 is provided with a first protective layer, and each first clamping cylinder 340 abuts against the cardboard 600 through the first protective layer. The second pusher assembly includes a second drive motor 410, a second lead screw 420, two second drive cylinders 430, and two second clamping cylinders 440. The second drive motor 410 and the second lead screw 420 are both mounted on the mounting bracket 100. The second drive motor 410 drives the second lead screw 420. A second slider 421 is slidably mounted on the second lead screw 420, and a second connecting rod is fixedly mounted on the second slider 421. One second drive cylinder 430 is located at one end of the second connecting rod, and the other second drive cylinder 430 is located at the other end of the second connecting rod. The air rod of each second drive cylinder 430 is connected to one of the second clamping cylinders 440. Each second clamping cylinder 440 is provided with a second protective layer, and each second clamping cylinder 440 abuts against the cardboard 600 through the second protective layer. The conveying assembly 500 is a conveyor belt.

[0022] In the above embodiment, the pusher device for preventing damage to the cardboard 600 further includes a control system, which is a PLC control system. The lifting cylinder 220, the first drive motor 310, the two first drive cylinders 330, the two first clamping cylinders 340, the second drive motor 410, the two second drive cylinders 430, and the two second clamping cylinders 440 are all electrically connected to the control system.

[0023] In other words, this pusher device needs to be used in conjunction with other cardboard 600 processing equipment. For example, it can be used with a cutting device, where the conveyor assembly 500 will convey the cardboard 600 to the cutting device for cutting.

[0024] In the initial state, the plug 211 is inserted into the socket 110, and the fixing pin 212 is inserted into the plug 211, thus fixing the rotating frame 210 to the mounting frame 100. In use, the operator removes the fixing pin 212, then rotates the rotating frame 210, moving the placement base 230 from its initial position to the other side. The operator then neatly places the stack of cardboard 600 onto the placement base 230. The rotating frame 210 is then rotated again, allowing the plug 211 to be reinserted into the socket 110, and the fixing pin 212 is inserted into the plug 211, thus fixing the rotating frame 210 to the mounting frame 100. Furthermore, under the control of the control system, the first pusher assembly and the second pusher assembly operate sequentially. That is, when the first pusher assembly picks up the cardboard 600 from the placement seat 230 and onto the conveyor belt, the second pusher assembly begins to prepare to pick up the cardboard 600. In other words, when the second pusher assembly picks up the cardboard 600 from the placement seat 230 and onto the conveyor belt, the first pusher assembly moves back to the position ready to pick up the cardboard 600.

[0025] In use, the control system starts the first drive motor 310, which in turn drives the first lead screw 320 to rotate, causing the first slider 321 to move closer to the cardboard 600. After moving to the preset position, the control system starts the two first drive cylinders 330. Each first drive cylinder 330 drives the first clamping cylinder 340 downward, causing the two first clamping cylinders 340 to move to the preset position, that is, the two first clamping cylinders 340 are located on both sides of the cardboard 600. Then, the two first clamping cylinders 340 are activated to clamp the cardboard 600. Then, the control system controls the first drive motor 310 to reverse, that is, to convey the clamped cardboard 600 towards the conveyor belt. Finally, it is located above the conveyor belt, and then the two first clamping cylinders 340 no longer clamp the cardboard 600, that is, the cardboard 600 can fall onto the conveyor belt for the next process. It is worth mentioning that when the two first clamping cylinders 340 move, the control system controls the second drive motor 410 to start, which in turn drives the second lead screw 420 to rotate, causing the second slider 421 to move closer to the cardboard 600. After moving to the preset position, the control system controls the two second drive cylinders 430 to start. Each second drive cylinder 430 drives the second clamping cylinders 440 upwards, causing the two second clamping cylinders 440 to move to the preset position, that is, the two second clamping cylinders 440 are located on both sides of the cardboard 600. Then, the two second clamping cylinders 440 are activated to clamp the cardboard 600. Then, the control system controls the second drive motor 410 to reverse, that is, to convey the clamped cardboard 600 towards the conveyor belt. Finally, it is located above the conveyor belt, and then the two second clamping cylinders 440 no longer clamp the cardboard 600, that is, the cardboard 600 can fall onto the conveyor belt for the next process. At the same time, the two first clamping cylinders 340 return to the preset position to prepare to clamp the cardboard 600. In this way, the clamping is continuous, and because of the first and second protective layers, the clamping process is both secure and does not damage the cardboard 600. This avoids damage to the edges of the cardboard 600, which could easily lead to defective products.

[0026] In summary, the above embodiments are not limiting embodiments of this utility model. Any modifications or equivalent variations made by those skilled in the art based on the substantive content of this utility model are within the technical scope of this utility model.
